TAXONOMY: Superfamily: Bombycoidea, Latreille, 1802 Family: Saturniidae, Boisduval, [1837] 1834 Subfamily: Saturniinae, Boisduval, [1837] 1834 or Attacinae, Blanchard,1840 Tribe: Attacini, Blanchard, 1841 Genus: Hyalophora, Duncan, 1841

DISTRIBUTION:

Hyalophora mexicana (approximate wingspan: males: 105-125mm; females: ?? // forewing length: males: 64-78mm; females: ??) flies in
Mexico: Sierra Occidental: Zacatecas; Guanajuato; at elevations between 1966-2300m.

This species has an almost uniform reddish-orange-brown ground colour and appears most similar to Hyalophora euryalus, but white cell markings are more rounded, less elongated than found in euryalus. It is a large species and has a reduced quarter circle band of blue scales in the apical ocellus, and relatively straight postmedian lines are not undulating.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

There is probably just one brood, with moths on the wing in July. There may be additional flight months (June and or August).

Caterpillars probably feed on a wide range of plants, but the natural host is unknown.

ECLOSION, SCENTING AND MATING:

Female moths extend a scent gland from the posterior of the abdomen at night, and males, flying into the wind, are able to follow the plume and locate the female.

EGGS, LARVAE, COCOONS AND PUPAE:

Females glue eggs singly or in clumps on leaves of the host plant.

The eggs hatch in 9-14 days and the caterpillars consume foliage.

The "assumed" bottle-shaped, double-walled cocoon is spun in the outer part of the host plant and is attached to a twig by only one-half its length, leaving the valved-neck free in the air.

Larval Food Plants

It is hoped that this alphabetical listing followed by the common name of an anticipated alternative foodplant will prove useful. Natural foodplant is unknown as of 2014. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
